I hope you're right and Sony do release the A20 series here in the U.S. towards the holiday season,
though i'm not holding my breath
my own skepticism is simply because Sony U.S. are just so difficult to gauge - for example, in 2012 we got the NWZ-F-800 series ,albeit sans the 64gb F807 model,yet the next year when the F-880 series were released everywhere else, for some reason the U.S. market were skipped over completely. and the same again in 2014 when the ZX-1 model was released and was sold just about everywhere on this planet other than in the United States - and yet Sony go ahead and offer the ZX-2 here so.....
? ha!
it's just hard to know why they do what they do.
for example why does Sony only offer America the A17 and only in Silver? and in Canada if i'm not mistaken Sony only offers the black model of the A10 series.who decides this stuff? heh..I mean - why not take advantage of such a massive market and offer both the A15 and A17 and in more colors? we could go even further back to the E,S,X,Z and original A series models some which were released in North America ,others which for some reason or another were not.
so , at the end of the day when it comes to Sony North America i tend to err on the side of caution ~ but again I hope I am mistaken and the A20 series does see release here.btw you have a keen eye ,i never caught the color correlation between the MDR-100AAP headphones and the A-25 Walkman series but they definitely do appear to be made to go with one another.
